The quality of back fillet is unrelated to the amount of solder.

Focusing on the 'optimal timing'! Also able to handle back fillets for through holes without any issues.

In industry common sense, it is considered better to increase the amount of solder to secure the back fillet of through holes. However, in our view, the amount of solder is not the issue; rather, it is necessary to create a condition where solder can easily flow into the through holes as a prerequisite. Specifically, it is essential to quickly introduce flux into the through holes before flowing the solder, and if this is not done, no matter how much solder is supplied later, an appropriate back fillet cannot be formed. If the importance of flux is overlooked, one may conclude that "the amount of solder is not adequate (insufficient)." Our robots focus on the "optimal timing" to make the most of the flux, allowing for proper handling of back fillets in through holes without any issues. *For more details, please refer to the PDF materials or feel free to contact us.*
